Access 2007 - Why won't Access work on workspaces/web folders?

So if I try to take an Access database that currently resides on a network shared drive (or try to create a brand new one for that matter) on a web folder of a "workspace", why won't it work? I have read, write modify permissions on t开发者_如何学JAVAhe folder I am trying to add it to, however I can errors, and it won't recognize the file type (.accdb or .mdb gets made .unk).

Could someone just explain the logic to me of why this doesn't work?

EDIT: So I guess I should include that on the shared drive there is a folder that houses the access front end file, and another folder within this folder that houses the BE tables file. I tried to reproduce what it one the shared drive in the web folder. I cannot even get the .mdb portion to work unless it's downloaded locally to my computer.

The easy way arround this problem is to use a ODBC DSN to access the database, (BE) and have the FE (front-end), in your local computer. This happens because MS-Access needs to lock the file while using it.

You should be able to work with the FE using SkyDrive and other services like it, cause they copy the file localy, and when you close the file they syncs it to the web folder.
